What subject line works for Pharmaceuticals invoice reminder emails (no response)?

Name the situation and the business object, not your excitement. Something like "Invoice [number] is past due ([amount])" outperforms "Just checking in" because a CTO can decide from the preview text whether it's worth opening. Keep it under 50 characters when you can.

How many times should I follow up with a CTO (no response)?

First reminder 3 days after due date, then 7 days, then a call. Wait 3 to 5 business days after the first note. Faster looks anxious. After that, send a breakup note and archive it. A CTO who wants it will answer a clean close more often than a fifth bump.

Should I apologize for sending an invoice reminder?

No. You can be polite without acting like asking to be paid is a favor. State the facts, offer help if something is blocked, and keep the next step obvious. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.

How long should I wait before following up on no response?

Three to five business days is the default. Go longer if they just came out of a known crunch like month-end, a launch, or a board week. Going shorter rarely increases replies. It just stacks your name in their ignore pile.

Is it okay to send this invoice reminder on LinkedIn instead of email?

Yes if this CTO is actually active there and the thread isn't about payment details. Keep the LinkedIn version even shorter. Don't paste the full email. One context line and one question is plenty. Name the stall they care about, offer one small next step, and stop before the thread feels like a sequence.
